问题描述

在小数点后的浮点数中，我只想显示两个值.

in float after decimal point i want to show only two value

推荐答案

使用printf [

Use proper format specification fields of printf [^]. For instance

float x = 1.237f;
printf("x=%8.2f\n", x);

如您所见(输出为x = 1.24)，该值将四舍五入.
:)

As you may observe (the output is x = 1.24), the value is rounded.

使用sprintf将浮点数格式化为具有所需格式的字符串.我以为你真的在用C，而不是C#?

use sprintf to format your floating point number into a string that has the format you desire. I assume you''re really using C, and not C# ?
